VEL'OCIPEDE.

SPECIFICATION forming part of Letters Patent No. 368,360, dated August16, 1887.

Application filed April 6, 1987. Serial No. 233,881. (No model.)Patented in England December 9, 1882, No. 5,882.

To (ZZZ whom it 771.0, concern.-

Be it known that I, J AMES RIGHARDTRIG- WELL, ofBriXton Rise, London,England, have invented a certain new and useful ImprovementinVelocipedes, of which the following is a specification.

The object of my improvement is to pro vide a device for confining theanti friction balls of ball-bearing steering-joints of velociro pedes totheir seats when the neck and head are disconnected, whereby the ballscan be conveniently introduced or removed at will.

I will first describe in detail a ball-bearing steering'joint embodyingmy improvement,

and then point out the nature of the said improvement in a claim.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference designatecorresponding parts in all the figures.

Figure 1 is a vertical sectional view of a vclocipcde steering-jointembodying my im provement. Fig. 2 is a plan View of the lowerball-bearing of said joint. Fig. 3 is a detail view of theball-retaining ferrule employed therein. Fig. 4 is avertical sectionalview of the upper portion of a steering-joint embodying my improvementin a modified form. Fig. 5 is a sectional view of the retaining-ferrule3o employed in the modification.

A designates the steering-head of a velocipede, B the neck on thebackbone jointed thereto, E E bearing-boxes for the neck, helddetachably in the ends of the head A, F a

lock-nut, and E an extension of the box E,en-

gaged by the lock-nut F.

Circular seats D, Fig. 1, or D, Fig. 4, are formed in the bearing-boxesEE, and corresponding circular seats on the ends ofthe neck 0 B for theanti-friction balls O, which are held between and bear uponsaid seats011 the neck and bearing-boxes when the joint is effected.

A ferrule, G or .G, is connected detachably to either the neck or thebox-seat of'each set of bearing-balls O in such a position that it 5will, together with the connected seat, loosely confine the greaterhalves of the balls, so that when thejoint is disconnected the ballswill be held to the said seat. The halls may at any time be removed orreplaced by detaching the ferrule from the seat to which it isconnected.

The ferrules G (shown in Figs. 1, 2, and 3) have the form of a ringandare fitted and held removably in recesses in the bearing-boxes.

The ferrule G (shown in Figs. 4 and 5) has the shape of a cap, withlateral apertures J, through which the lesser portions of the balls 0project, and is connected detachably to the seat B on the neck by ascrew, H, passed through the top of the cap into the end ofthe 6o neck.

Detachable ferrules in this way may be arranged to confine two or moreindependent sets of balls.

Having thus described my invention. what I claim as new, and desire tosecure by Letters Patents, is-

In ball-bearing steering-joints of velocipedes, a retaining device forthe anti-friction balls, consisting ofa ferrule connected dctach- 7oably to a seat of the balls and together with said seat looselyconfining the greater halves of the balls, substantially as described.
